The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.

Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.

Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.

Shipping Weight

The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width &amp; height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

Discussion: Advanced B Complex was designed to provide the most advanced forms of B vitamins in the most scientifically discerning ratios available. Advanced B Complex contains Benfotiamine, a form of vitamin B1 that is five times more bioavailable than other forms of thiamin, as well as Pyridoxal-5-phosphate (P5P), Methylcobalamin and L-5-Methyltetrahydrofolate, bio-active forms of vitamin B6, B12 and folic acid respectively.

Suggested Use

Adult Dosage: Take 1 capsule one to three times daily with food, or as directed by a qualified health care practitioner.

Many brands claim to have the right the balance of the essential "Vitamin B's", but not wanting to wasting money, I have read the amounts that are necessary and balance that off against what is important and relevant. More importantly is how many servings do I need to take to get the level that my body requires. Advanced Series has produced a winner here, and having B1, B2, B3, B5, B6, and the added Folic Acid in its capsule all with a high content only requiring "1 Capsule" per serving is great.
